Claims.

1n Germany May 15, 1931 (Granted under section 14, act of March 2, 1927,

This invention relates to improvements in the treatment of spools of artificial silk and the like. In the manufacture of articial silk according to a spool spinning process, the freshly spun thread is wound on spools and is then subjected to several wet treating steps, such as Washing, bleaching, desulphurizing, etc. Heretofore, to carry out these treatments, the spools have been placed on rigid plates provided with openings and a plurality of such plates are stacked one on the other. Treating liquid is then forced through the spools. Due to the fact that, in practice, it is impossible to obtain spools of the same size, a satisfactory seal cannot be maintained between the spools by the use of such an arrangement.

It is, therefore, an object of this invention to provide an improved apparatus for use in the uid treatment of spools of artificial silk and the like.

Another object of this invention is to provide an improved arrangement for stacking spools of artificial silk so that there will be no leakage of the treating liquid between the spools of each stack.

A further object of this invention is to provide, in a spool treating apparatus, a flexible or elastic packing plate for use between the spools of each stack so arranged as to form a liquid tight sealtherebetween at al1 times during the treatment of the silk.

A still further object of this invention is to provide, in a spool treating apparatus, flexible or elastic packing means which will compensate automatically for any irregularities in the size of the spools, thus maintaining at all times a liquid tight seal therebetween.

These and other objects of this invention will become more apparent from a study of the following description and by reference to the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of the treating apparatus;

Figure 2 is a top plan view of one of the packing plates; K Figures 3 and 4 are detailed views of modified methods of construction of the openings formed in the packing plates to permit the passage of liquid through the spools without leakage.

Referring now more particularly to the drawings, in which like numerals indicate like parts, the treating apparatus designated generally by the numeral is mounted on wheels 11 running on tracks or rails'12 so that the treating apparatus may be moved from one treating station t'o 55 another in the course of treating the spools,

The wheels are secured in any suitable manner to a bottom plate 13 upon which the spools 14 are placed in several layers or tiers. The layers of spools are separated from each other by the packing plates 15 which are made from rubber or othersuitable material and which are provided with holes 16. The spools are arranged in such a manner that they are located concentrically with respect to the holes formed in the plates so that each stack of spools forms a tube through which the treating liquid may be forced from the supply ducts 17 which communicate with a distribution pipe 18 connected to the liquid supply means 19.

Each packing plate consists of a rigid frame 20 provided at each corner with openings 21 so that the said plates may be supported on the columns 22 supported on the bottom plate, thereby preventing any displacement thereof. The flexible plate is made of rubber or any other suitable material and is secured to the frame in any desired manner. The packing plate may be either solid, or hollow. If the latter form is used, the plates will become inflated during the treating of the thread by means of the pressure of the treating liquid, thereby effecting a positive packing of the spools. To prevent a collapse of the hollow plates which may occur if no liquid under pressure is contained therein, separator may be used.

Referring now more particularly to Figure 3, there -is shown in detail the manner in which the openings are formed in the plates. As will be noted, the middle of the plate surrounding each opening is increased in size, thus forming a shoulder 28 on the top and bottom thereof. These shoulders act as means to center the spools properly during the stacking thereof in the treating apparatus.

In Figure 4 there is shown a modified method of 95 forming the openings in the plates. A groove 24 is formed in the wall of each opening, thus providing an upper and lower enlargement 25 and 26. As soon as the treating liquid is forced through the spools, the pressure thereof will force these enlargements apart thus centering the spools and providing a liquid tight seal therebetween. The packing plates are formed as flat basins, as is clearly shown in Figure 1, and which are connected to each other by pipes 27. The treating liquid which has been forced through the spools is collected by the plates and is discharged through these pipes into a channel 28. To compensate for the pressure of the treating liquid, a weight 2 9 is placed on the cover, that is, the up- 110 permost plate. This cover preferably consists of rigid material and is lined on its lower or under surface with rubber or the like which bears against the top layer o f spools.

From the above description, it will be appreciated that there has been provided a simple and eicient arrangement for treating spools which is easy to handle and provides a satisfactory packing of the tiers of spools. By the use of flexible or elastic packing plates, a liquid tight seal is formed between the spools preventing any leakage of the treating liquid therebetween with the consequent loss in pressure. The flexible or elastic plates are secured to rigid frames so that they may be supported easily by vertical columns.

What is claimed as new is:

1. Apparatus for the wet treatment of` spooled Vartificial silk comprising a frame, a plurality of spool carrying plates supported by said frame one above the other and having a plurality of openings formed therein over which'the spools are placed, said openings having concentric shoulders formed integrally on the upper and lower surfaces of the said plates for centering the spools, each plate comprising a rigid frame having secured thereto a sheet of elastic material,. said plates forming a seal between the spools of each stack, and means to force liquid through each stack of spools and through the thread carried thereby.

2. Apparatus for the wet treatment of spooled artificial silk comprising a frame, a plurality of spool carrying plates supported by said frame one above the other and having a. plurality of openings formed therein over which the spools are placed, the spools being arranged in vertical stacks, the wall of each opening being provided with a groove whereby when liquid is forced therethrough the pressure thereof will force the upper and lower portion of the wall of each opening apart to provide a seal between adjacent spools.

3. Apparatus for the wet treatment of spooled artificial silk, comprising a rigid frame, a plurality of dish shaped flexible spool carrying plates supported by said frame one above the other, and having a plurality of openings formed therein over which the spools are placed, said openings having concentric shoulders formed integrally on the upper and lower surfaces of the plates for centering the spools, the spools being arranged in vertical stacks, said plates forming a. seal between the spools of each stack, communicating discharge pipes associated with said plates, and means to force liquid through said stacks.

4. Apparatus for the wet-treatment of spooled artificial silk, comprising a frame, a plurality of spool-carrying plates supported by said frame one above the other, each plate comprising a rigid frame having secured thereto a plate of exible material provided with openings over which the spools are placed, the upper and lower surfaces of the plates around each opening adapted to form shoulders which act as sealing means between the spools of each stack when treating liquid is forced therethrough.

5. Apparatus for the wet-treatment of spooled artificial silk and the like, comprising a frame, a. A

plurality of spool-carrying plates supported by said frame one above the other and having a pluralityof openings formed therein over which the spools are placed, the inner faces of said openings being slit whereby when liquid is forced therethrough the pressure thereof will force the upper and lower portions of each face apart to form shoulders to provide centering means for the spool, said plates forming a seal between the spools, and means to force liquid therethrough.
